Cylindrical Heating Systems

IMS Cylindrical Heating Systems provide a unique solution which is best utilized for the continuous thermal processing of pumpable heat and shear sensitive, high viscosity, and multiphase materials that demand precise temperature control.

Planar Heating Systems

IMS Planar Heating and Drying Systems can offer a better alternative to conventional, re-circulated hot air dryers due to the best-in-class uniformity, efficiency and thermal processing they demonstrate in many industrial processes.

Cylindrical Heating Systems

Although an IMS CHS can be used for many product and process applications, including heating, cooking/gelation, pasteurization and sterilization, its specific benefits and economic advantages are best achieved when applied to heat or shear sensitive, high viscosity and multi-phase fluids.

Planar Heating Systems

An IMS Planar Heating System has advantages over conventional dryers in two areas of their design that are intrinsically inefficient: (1) pre-heating a product to evaporative temperature, and (2) removing water from products with relatively low overall moisture content.
